Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing welding machines for thermal combination of material railways often face challenges with stability, especially when welding near edges, and require complex maintenance, which can increase susceptibility to repairs and reduce reliability.
Innovation Solution
The proposed welding machine incorporates a telescopic extract mechanism that allows the heating device and pressure roller to be moved parallel to the transverse axis, enabling easier handling, reduced maintenance, and improved stability, especially when welding near edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If ground-level hot-air welding machines have additional support wheels spaced as far apart as possible to increase stability, then stability against lateral tipping is improved, but support wheels get in the way and prevent welding close to the edge
Solution Approach 1:
The support wheels are made movable relative to the machine body through a telescopic support structure. This allows the support wheels to be dynamically repositioned - extended outward when stability is needed, and retracted inward when welding close to edges is required, thus resolving the contradiction between stability and adaptability
2Stability of the object's composition
If fixed support wheels are used to provide stability, then stability is improved, but the machine cannot adapt to different welding positions and edges
Solution Approach 1:
The support structure transitions from a fixed configuration to a dynamic one with telescopic support wheels that can be extended and retracted, allowing the machine to adapt its support configuration based on the welding task requirements
3Stability of the object's composition
If complex support structures are added to improve stability, then stability is improved, but device complexity increases and maintenance becomes more difficult
Solution Approach 1:
The telescopic support structure uses a nested configuration where inner support elements are housed within outer structural components. This nesting approach provides the necessary stability and adjustability while minimizing the overall structural footprint and reducing complexity compared to fully extended support structures
Solution Approach 2:
The dynamic telescopic mechanism provides stability adjustment without requiring multiple fixed support structures, reducing overall device complexity while maintaining the ability to adapt to different welding scenarios
